ADJUSTABLE INK-ROLLER TRUCK.

SPECIFICATION forming part of Letters Patent No. 733,955, dated July 21,1903.

Application filed October 2, 1902.

To all whom it may concern:

Be it known that we, MERRITT GALLY and J OSEF HREN, residing atBrooklyn, in the county of Kings and State of New-York, citi- Zens ofthe United States, have jointly invented a new and useful AdjustableInk-Roller Truck,of which the followingis a specification.

Our invention relates to the adjustment of inking-rollers to positionfor the proper inkin g of forms for printing, &c.; and it consists inproviding suitable means for adjusting the ink-roller trucks, securingproper relative diameters to the composition rollers, providing for thechange in diameter of composition rollers when shrunken by drying out orwhen expanded by moisture.

In the accompanying drawings, Figure l is an edge View of the adjustableroller-truck Fig. 2 is a side view showing a section of the expansibleand contractible rim or tire. Fig. 3 is a sectional view of the truck,showing the relative position of its parts. Fig. 4 is an enlarged viewof a part of the coiled-spring tire, showing the means of joining theends of the coil together to form the circular rim for the truck. Fig. 5is an end view, and Fig. 6 a side view, of the connecting screw-plug.Fig. 7 is a cross-section of the expansible and contractible rim and apart of the beveled disks, showing the manner of expanding the rim byarrangement of the position of the disks. 7 Fig. 8 is a bent-wirewrench-pin for turning the set-nuts of the truck for adjustment. Fig. 9shows the truck with tworims ortires to increase the tread 0f the truck.Fig.10 shows the rim of the truck flattened to increase its frictionalcontact with the bearer. Fig. 11 shows the adj usting-block with handlefor adjusting the roller-trucks with face of rollers type-high or toproper pressure on the form. Fig. 11 shows the locking device forpreventing derangement of adjustment of the truck. Fig. 12 is same asFig. 11 in modified form. Fig. 13 shows one of the disks of the truckbeveled and the other disk plane-faced, and Fig. 14. shows both of thedisks oi the truck plane-faced with the truck on the journal of theink-roller.

The ink-roller R, (partly shown in Fig. 14,)

Serial No. 125,891. (No model.)

has journals, as O, and on these journals are placed the adjustableroller-trucks.

The general features of the truck are shown in Figs. 1, 2, 3, the truckbeing made up of two disks B c, a thimble or hub O, and an expansibleand contractible rim or tire F. The rim may be made of coiled wire, asshown, or of other elastic or expansible and contractible material. Asshown in Figs. 1, 2, 3, the rim F is made of coiled wire, like aclosely-wound spring. The ends are brought together, forming a ring tobe used as a tire for the truck. Theends of the coil to form the tireare fastened together at g, Fig. 2, the fastening parts being shownenlarged in Figs. 4, 5, 6. A short screw-plug is placed within andbetween the ends of the coil, one or more of the turns of each end ofthe coil forming male threads to fit the female screw-plug. Fig. 4 showsa piece of the coiled tire with the screwplug g screwed partly into oneend of the coil, the other part of the plug remaining to fit into theother end of the coil to hold the ends together. plug, showing thecentral body portion G squared, as g, to be held by vise or pincers whenscrewing the plug into the first end of the coil. The other end of thecoil is turned backward, while holding the plug firmly, twisting thecoil sufficiently to have its reaction screw the last end of the coilonto the projecting end of ,the plug, thus bringing the two ends of thecoil together, the inserted screw-plug holding them rigidly connected.

The two disks B andc, Fig. 1, are beveled at their edges, so that theyform a V-shaped -groove on the edge of the truck for receiving 'theelastic tire F. A thimble A is attached to or forms a part of the disk Band passes through the center of the disk 0. The thimble or hub A has ascrew-thread out thereon, and the hub c of the disk 0 has a femalethread in its bore to match the male thread on the thimble A. The disksB and c are brought nearer to each other or farther apartjbyfturning thedisk 0 with the removable'pinwrenoh E, Fig. 8, inserted inpin-holescgrFig. 1. A set-nut D, to be turned by means of the pinwrenchE, is used to prevent the disk 0 from turning after being set untilanother adjust- Fig. 5 is an end view of the able disk is free foradjustment.

ment is required. Pin-holes d in the setuut are for use in connectionwith the pinwrench E.

When the disks B and care brought nearer together, the bevels of theiredges form a sharper V and expand the tire F, increasing the diameter ofthe tire to correspond with the diameter of a larger ink-roller. Whenthe disks are set farther apart, the V is made wider and allows the tireto become smaller in diameter to correspond with a smaller or shrunkenroller, as shown by Fig. 7.

The roller-trucks usually roll on bearers about type-high, forming apart of the press, each side of'the type-form or separately placedwithin or at the side of the form, so that the face of the rollers willtouch the face of the form with just the amount of pressure to properlyapply the ink, and as composition inkingrollers are subject toconsiderable shrinkage and expansion from time to time it is verydesirable to have adjustable trucks to accommodate these changes.

We are aware that roller-trucks with a single beveled bearing edgeresting on an oppositely-beveled bearer for adjustment by shifting toright or left on the bearer have been used; but these are objectionable,as they require a wider-faced bearer and require a change in the pressitself when applied to it and must be set out of line from a propertread in relation to other parts of the machine. What seems desirable tous is a rollertruck adjustable within itself and applicable to any presshaving ordinary bearers, and this is what we have produced by ourinvention as so far described.

To increase the frictional tread of the truck to avoid slipping, thetruck may be made of a greater number of disks and a greater number oftires combined, as shown in Fig. 9, in which F F are two tires, B andfare additional disks, h and h are set-nuts, and A A represent a doublescrew-thimble. From the figure, as shown, the combination will bereadily understood.

Fig. 10 shows a modification of Fig. 1, the tire being flattened toincrease its frictional rolling-tread. Fig. l1 shows means for lookingthe movable disk after setting to position without the set-nnt. Groovesa a, a a are cut into the thimble or hub A, and the tooth of aspring'catch when inserted in any one of these grooves prevents theadjustable disk from turning on the screw -thiu1ble. The toothed catch yhas in Fig. 11 a fingerlever y, by means of which it may be turned onits axis. A beveled cam t' is cut into the face of the hub O, and as thelever 3 is swung on its pivot the tooth of the catch is withdrawn fromthe groove in the screw-thimble and the mov- After ad- The spring 8holds In Fig. 12 the lever is placed on the side of the hub C and has onit a lifting-cam articulating with the surface of the screw-thimble tofree the catch-tooth.

Fig. 13 shows the truck made with one beveled disk and one plane diskinstead of two beveled disks and is simply a modified form of theinvention.

Fig. 14 shows both disks plane, the expansible and contractible rimbeing pinched between them more or less to produce the expansion andcontraction, as will be seen from the two parts of the figure, the disksbeing B B, the tire F F. The thin hubs Z Zprevent the elastic tire ofthe truck from expanding inwardly, limiting the expansion to theincrease of diameter of the tire.

The adjustable trucks are not only applicable to form-inking rollers,but to any inkrollers on which such trucks are of use, and we claimtheir invention for such purpose.

Fig. 11 shows a test-block used in combination with the adjustableroller-truck for accurately setting the truck.

The best time to set the roller-trucks to their proper diameter is whenno type-form is in the press, as the face of type-form is often made upof parts and sometimes does not reach near to both of the trucks and insuch cases does not provide in itself proper means for alining theink-roller. For the purpose of quickly and accurately adjusting thetrucks to proper diameter we use the test-block, Fig. 11, when no formis in the press. This tester consists of a type-high block N with handleLM. The rollers being rolled to the position over the form-bed, theblock is slid along the face of the bed until it comes under the ink-'roller or in contact therewith. The edge at of the block is beveled orrounded to avoid abrading the face of the soft roller, and being passedunder the roller near the truck the truck is changed in its diameteruntil it touches the bearer on which it is to roll. Both ends of theroller must be then adjusted. The test-block then being removed and thetypeform placed on the face of the bed, the adj ustment is proper foroperation, determining the amount of pressure desired on the face of theform by the pressure on the test-block. The desirability of the use ofthis test-block in setting the trucks will be apparent when it isconsidered that many type-forms occupy only a small portion of one sideor center of the face of the press-bed, and it would be very difficultto set the two end trucks on such form and secure an exact alinementwith the face of the form. By using the test-block near each and both ofthe trucks at the extreme ends of the roller and setting both exactlyalike alinement with the face of the form will be absolute.

The bevel of the test-block serves not only for preventing injury to thetender surface of the soft composition form-roller, but also whensetting the trucks in determining the pressure of the roller on theform. Thrusting only the bevel under the roller and setting the truckthereto, the position of the roller on the bevel will determine thepressure of the roller.
